Thanks - I've tried two different motors and all the foot controllers that plug into the configuration. Same with every combo. I'll try letting it spin then put a bit of drag on it and see what it does. It is clean and moves freely. Maybe it needs more cleaning or something.
I've freed up countless 401s - I've seen some stuck up pretty much like glue. I can't remember this machine from when I cleaned it initially. I just went to check it before someone came to look at it and the dumb thing was was acting like that. Fortunately I had another one to sell the lady. When she left we fooled with the controllers and motors for a while. I'm thinking it may be time to get serious with some heavy duty cleaning down there in the gears.
